With ad campaigns and business ventures complementing multimillion-dollar tours, it's no surprise that Jay-Z and Beyoncé have plenty of money (after all, there's a rumor that they now have a $4 million private island), but now there's a rough number on their wealth -- and it looks like a record.

The 31-year-old Beyoncé is raking in millions from her "Mrs. Carter" show tour, which began Monday night in Serbia. The Daily Star reports that Beyoncé is set to earn approximately $116 million from the world tour.

Meanwhile, Jay-Z has earned millions as co-owner of the 40/40 club, which has two locations in New York, and is reportedly selling his small share with the NBA Brooklyn Nets to extend his Roc Nation Sports representation business into basketball, according to Yahoo Sports.

With $1 billion, Jay-Z could certainly afford the $4 million private island that he is said to have bought in the Bahamas for his family.
